Gravity Probe B

Testing Einstein's Universe

WEEKLY HIGHLIGHTS FOR WEEK ENDING 3 MARCH 2000:

STANFORD HIGHLIGHT
Lockheed Martin has completed a set of position measurements on Probe C on
the 4 external HEX locations and on 2 of the internal heat station
locations. The data show that the inside and outside locations agree to
better than about 0.030 inches. These data eliminate an inside-to-outside
offset as the root cause for the thermal anomaly at heat transfer locations
#3 and #4. Detailed analysis of the data are ongoing.

be random vibration testing in LMMS B/181 in Sunnyvale.
